## Background
BACKGROUND
The embodiments disclosed within this specification relate to electronic mail (e-mail) systems. Communication via e-mail has become ubiquitous throughout the industrialized world. Indeed, e-mail communications are now commonly replacing communications that, prior to the advent of e-mail communication systems, were predominantly relayed via letters, telephone calls and facsimile transmissions.
There are a variety of methods currently used to access e-mail. One method that is commonly used is for a user to access an e-mail account using an e-mail client instantiated on a processing device, such as a computer or a personal digital assistant. The other method that is oftentimes used is for a user to use a web browser to navigate to particular web site where e-mails are stored, and then log into the web site using a user name and password.
That said, the paradigm for e-mail access tends to be adynamic. Oftentimes, in order to share an e-mail with other users, a user who received the e-mail must forward the e-mail to others with whom that e-mail user desires to share the e-mail. Thus, the user receiving the e-mail must not only take the time to forward the e-mail, but also ensure that the e-mail is forwarded to the proper people. If the user inadvertently types in, or selects, an incorrect e-mail address, the intended recipients of the forwarded e-mail may not receive the e-mail.
BRIEF SUMMARY OF THE INVENTION
The embodiments disclosed within this specification relate to electronic messaging systems. One embodiment of the present invention can include a method of federating electronic mail (e-mail). The method can include receiving a request from a first user to view at least one e-mail of a second user, the request including at least one identifier corresponding to the second user and criteria indicating a subject matter of the e-mail. The method further can include verifying whether the first user is authorized to access the e-mail of the second user that satisfies the criteria. Responsive to determining that the first user is authorized to view the e-mail of the second user that satisfies the criteria, the first user can be provided access to view at least one e-mail that satisfies the criteria.
Another embodiment of the present invention can include a system of that federates e-mail. The system can include a processor that receives a request from a first user to view at least one e-mail of a second user, the request including at least one identifier corresponding to the second user and a criteria indicating a subject matter of the e-mail.

Embodiments disclosed herein relate to a federation of electronic mail (hereinafter “e-mail”). E-mails that are received may be shared among not only the intended recipient, but also other e-mail users who may have an interest in the subject matter of such e-mails. For example, a first user can submit a request to view e-mails of a second user. The request can include at least identifier corresponding to the second user and criteria indicating a subject matter of the e-mail. The criteria can, for instance, indicate a subject identified in the e-mail, content contained in the e-mail (e.g., terms contained in a subject line and/or a body of the e-mail), features of e-mail attachments, certain e-mail senders, certain e-mail recipients, or the like. A verification process can be implemented to determine whether the first user is authorized to access the e-mail of the second user, and whether e-mails received by the second user satisfy the criteria. When the first user is authorized to view the e-mail of the second user, and e-mails are received that satisfy the criteria, access to view such e-mails can be provided to the first user.
FIG. 1 is a first block diagram illustrating a communication system 100 for federating e-mails in accordance with one embodiment of the present invention. The system 100 can include a communication network 102. The communication network 102 can comprise a local area network (LAN), a wide area network (WAN), the Internet, or any other network(s) suitable for communicating electronic data. As such, the communication network 102 can include wired communication links, wireless communication links, fiber optic communication links, or any other communication links suitable for communicating data. As those skilled in the art will appreciate, the communication network 102 can include any of a variety of network servers, routers, switches, access points, base transceiver stations, repeaters, and the like. Moreover, any suitable communication protocols can be implemented in the communication network 102, and the invention is not limited in this regard.
The system 100 also can include a processing device 104 on which an E-mail server 106 is instantiated. The e-mail server 106 can be embodied as an application or other suitable program code. In illustration, the processing device 104 can be a computer dedicated for hosting the e-mail server 106, or a computer that also hosts other applications, for example an application that functions as a domain controller, a file server, etc.
The system 100 also can include one or more communication devices 108, 110. The communication devices 108, 110 can be embodied as computers, mobile computers, netbooks, personal digital assistants, mobile telephones, mobile radios, internet devices, or any other devices on which e-mails communicated via the communication network 102 can be presented for viewing.
In one embodiment, one or both communication devices 108, 110 can include e-mail client applications 112, 114 for managing e-mail communications on the respective communication devices 108, 110. For example, the e-mail clients 112, 114 can receive e-mails, store e-mails, present e-mails for viewing, present user interactive views for generating e-mails, and so on, as is well understood by the skilled artisan. In addition, the e-mail clients 112, 114 can include any of a myriad of menus and toolbars for managing e-mails, and implementing the methods presented herein, which will be described in greater detail.
In another embodiment, one or both communication devices 108, 110 can include a respective web browser via which users can access the e-mail server and/or remotely located e-mail clients. For example, via a web browser instantiated on the communication device 108, a user can access an e-mail client located on another communication device (not shown), or a user can access the e-mail server 106.
In yet another embodiment, one or both communication devices 108, 110 can include a remote desktop which may be used to access another communication device (not shown) on which an e-mail client is instantiated or to access the e-mail server 106. Remote desktops also are well known in the art.
In operation, when it is desired for a first user 116 to access selected e-mails of a second user 118, for example to view such e-mails, an e-mail view request 120 can be generated. The e-mail view request 120 can include at least one identifier corresponding to the second user, and criteria for selecting the e-mail. As noted, the criteria can indicate a subject identified in the e-mail, content contained in the e-mail (e.g., terms contained in a subject line and/or a body of the e-mail), features of e-mail attachments, certain e-mail senders, certain e-mail recipients, or the like. The e-mail senders and/or e-mail recipients can be identified based upon their e-mail addresses, domains from which, or to which, the e-mails are sent, and so on.
Features of e-mail attachments also can be indicated by the criteria. For instance, the criteria can indicate a type of e-mail attachment, content contained in the e-mail attachment, and so on. In one aspect of the present invention, the criteria also can indicate features of diagrams and/or photographs contained in attachments. For instance, image processing techniques known in the art can be applied to such diagrams/photographs to identify features in the diagrams/photographs, and the identified features can be compared to the criteria. Still, the criteria can indicate any other features of e-mails and/or attachments, and the invention is not limited in this regard.
In one embodiment, the e-mail view request 120 can be communicated to the e-mail server 106. In another embodiment, the e-mail view request 120 can be communicated to the communication device 110. The e-mail view request 120 also can be sent to any other suitable communication device. The e-mail view request 120 can be communicated from the communication device 108 at the behest of the first user 116, communicated from the communication device 110 at the behest of the second user 118, communicated from the processing device 104 at the behest of an administrator, or communicated by any other authorized person from any suitable device.
When the e-mail view request 120 is received, the e-mail server 106, e-mail client 114, or another suitable application can process the e-mail view request 120 to verify whether the first user 116 is authorized to access the e-mail of the second user that satisfies the criteria contained in the e-mail view request 120. Such verification can be performed in any suitable manner. For example, a user profile associated with the first user 116 can be processed by a suitable device (e.g., a communication device 108, 110, the processing device 104, or another device) in order to determine whether the first user 116 is authorized to view e-mails satisfying the criteria identified by the e-mail view request 120. A user profile associated with the second user 118 also can be processed by in a similar manner to determine whether the first user 116 is authorized to view such e-mails. The respective user profiles can be maintained by the e-mail server 106, a domain controller (not shown), or otherwise made accessible to the appropriate device in a suitable manner.
When the first user 116 is authorized to view e-mails of the second user 118 that meet the specified criteria, e-mails directed to the second user 118 can be processed to determine whether they meet the criteria. Such processing can be performed by the e-mail server 106, the e-mail client 114, or another suitable application when the e-mails are received. In illustration, the subject line and/or the body of the e-mails can be parsed to identify content contained in the e-mail, and a determination can be made whether any such correspond to the criteria. Such content can include textual content, alphanumeric content, symbolic content, and the like.
In another embodiment, the e-mail address of the sender can be identified and a determination can be made whether that e-mail address corresponds to the criteria.
In yet another embodiment, attachments can be processed to determine whether they correspond to the criteria. As noted, such processing can include parsing content in the attachments, performing image recognition on photographs and/or diagrams contained in the attachments to determine whether features contained in the photographs/diagrams correspond to the criteria, and so on. It will be appreciated by those skilled in the art that such attachments can be file attachments, but also may be attachments that are embedded within the e-mail, for example as photographs/images pasted into the body of the e-mail.
When e-mails directed to the second user 118 are received, the e-mails meet the specified criteria, and the first user 116 is authorized to view such e-mails, those e-mails can be made available for viewing by the first user 116. In this regard, the e-mails directed to the second user 118 that are made available for viewing by the first user 116 can be classified as federated e-mails 125. As used herein, the term “federated e-mail” means an e-mail directed to a second user that is automatically accessible for viewing by a first user based on specified criteria related to the e-mail.
In illustration, if the e-mail server 106 is performing the aforementioned processing of the e-mails, the e-mail server 106 can retain the federated e-mails 125 for the first user 116. For example, the federated e-mails 125 can be placed in a directory that the first user is authorized to access. The federated e-mails 125 also can be forwarded to the e-mail client 112, for example when the e-mail client 112 synchronizes with the e-mail server 106. Accordingly, the first user 116 can view the federated e-mails 125 in the e-mail client 112 and/or view the federated e-mails 125 by logging into the e-mail server 106.
In one aspect of the present invention, the federated e-mails 125 can be placed into one or more particular folders. Such folders can be defined by the first user 116, the second user 118 and/or an administrator. For instance, the first user 116 or an administrator can create a folder in the e-mail server 106 and/or the e-mail client 112 in which to place all federated e-mails 125. In another embodiment, the second user 118 or an administrator can create a folder in the e-mail client 114 in which to place all federated e-mails 125. Other federated e-mails for which the first user 116 is provided access also can be placed in the same folder, or a folder can be created for each of the users whose federated e-mails are available to be accessed by the first user 116.
In another embodiment, folders can be created for various subject matters. So, federated e-mails 125 pertaining to a first subject can be placed in a first folder, federated e-mails 125 pertaining to a second subject can be placed in a second folder, and so on. The subjects to which the various federated e-mails 125 pertain can be identified when the e-mails are parsed to identify the content, as previously described.
Further, based on the identified content, identifiers that indicate the subject matter of the federated e-mails 125 can be generated and associated with the federated e-mails. The identifiers can be embedded in the federated e-mails 125 as metadata, placed in the subject line of the federated e-mails 125, or associated with the federated e-mails 125 in any other suitable manner. The identifiers can be used not only to facilitate identification of the subject matter by the first and/or second users 116, 118, but also to facilitate organizing operations performed on the federated e-mails 125. For instance, when a particular project is complete, the identifiers can be used to identify federated e-mails 125 associated with that project for the purpose of archiving or deletion. Notwithstanding this example, the identifiers can be used for any other types of organization performed on the federated e-mails 125.

FIG. 4 is a flow chart illustrating a method 400 of federating e-mail in accordance with another embodiment of the present invention. At step 402, a request from a first user can be received to view at least one e-mail of a second user. The request can include at least one identifier corresponding to the second user and a criteria indicating a subject matter of the e-mail.
At step 404, an e-mail can be received. At step 406, the e-mail can be parsed to determine whether the e-mail satisfies the criteria. For example, the e-mail can be parsed when it is received, or at a later point in time. Referring to decision box 408, a determination can be made as to whether the e-mail satisfies the criteria and whether the first user is authorized to access the e-mail. If not, at step 410 the e-mail can be provided exclusively to the second user.
If, however, a determination is made that the e-mail satisfies the criteria and the first user is authorized to access the e-mail, than at step 412 the first user can be provided access to view the e-mail. In one embodiment, an identifier can be associated with the e-mail to indicate the subject matter of the e-mail. The identifier can be embedded in the e-mail, for example as metadata, such as a meta tag. Further, a first folder in an e-mail client of the first user and/or a first folder in an e-mail client of the second user in which to place the e-mail can be identified. The first folder can be distinct from a second folder in which at least one other e-mail received by the first user is placed. For instance, federated e-mails pertaining to a first subject can be placed in a first folder, and federated e-mails pertaining to a second subject can be placed in a second folder.
